Abstract
В радиолокационной станции с одновременной двойной поляризацией используется радиочастотный делитель (21) мощности вместо быстродействующих переключателей двух поляризаций, используемых в современных радиолокационных станциях с двойной поляризацией. Предложенные станции обеспечивают передачу и прием горизонтально и вертикально поляризованных сигналов одновременно, при этом критические компоненты приемника в основании радиолокатора перенесены выше вращающегося угломестного соединителя (34). Используется также обходной (25a,b) переключатель для переключения режимов радиолокационной станции, и конструкция (21a,b; 22; 39; 41; 38; 24) для приема сигналов с двумя поляризациями, позволяющая осуществлять экономичный сбор данных о коэффициентах деполяризации для выбранных атмосферных областей. Эти новые конструкции устраняют проблемы длительного времени анализа и уменьшенных диапазонов скоростей в современных радиолокационных станциях с двойной поляризацией и исключают относительно дорогой и ненадежный переключатель поляризации.The radar with simultaneous double polarization uses a radio frequency divider (21) of power instead of high-speed switches of two polarizations used in modern radar stations with double polarization. The proposed stations provide for the transmission and reception of horizontally and vertically polarized signals at the same time, with the critical components of the receiver at the base of the radar shifted above the rotating elevation connector (34). A bypass switch (25a, b) is used to switch between modes of the radar station, and a design (21a, b; 22; 39; 41; 38; 24) for receiving signals with two polarizations, allowing economical collection of data on depolarization coefficients for selected atmospheric areas. These new designs eliminate the problems of long analysis times and reduced speed ranges in modern dual-polarization radar stations and eliminate the relatively expensive and unreliable polarization switch.
